Indigo Snakes vs. Rattlesnakes
The Eastern Indigo snake is a predator for a rattlesnake. Unlike many non-poisonous snakes, the Indigo snake is not a constrictor.
Therefore, the Indigo snake overpowers the rattlesnake with its muscular jaws and swallows it alive. During this process of killing a rattlesnake, the Indigo snake takes the bite of the rattlesnake. The venom of rattlesnake doesn't kill an Indigo snake as it is immune to rattlesnake's venom.
